[0019] Specifically, please refer to Figs. 1 to 3 , Fig. 1 The overall structure schematic diagram of the crushing device for granular feed raw materials provided by the embodiment of the present application is shown in the figure. Fig. 2 The cross-sectional structure schematic diagram of the crushing box provided by the embodiment of the present application is shown in the figure. Fig. 3A side cross-section structure schematic diagram at the transverse partition plate is provided for the embodiments of the present application. The pulverizing device 100 applied to the granular feed raw material comprises a pulverizing box 110, and the specific structure and material of the pulverizing box 110 can be set according to the actual situation. It can be understood that, since the upper grinding disc 120 and the lower grinding disc 150 are usually disc-shaped, in order to better match the upper grinding disc 120 and the lower grinding disc 150, the inner cavity cross-section shape of the pulverizing box 110 can be set as a circle. The upper grinding disc 120 is rotatably arranged in the pulverizing box 110, and the upper grinding disc 120 is a driving grinding disc, which can be rotated under the driving of the driving device, so that the granular feed between the upper grinding disc 120 and the lower grinding disc 150 is extruded into a granular shape. The outer side bottom of the upper grinding disc 120 is provided with an annular groove 121, and the inner wall of the pulverizing box 110 is provided with an annular shelf 111, and the inner side of the annular shelf 111 extends to the annular groove 121. The annular shelf 111 is used for bearing and limiting the upper grinding disc 120, so that the upper grinding disc 120 can rotate along the central shaft without changing the horizontal height. The upper grinding disc 120 is linked with a driving device 130 for driving the upper grinding disc 120 to rotate along the central shaft, and the driving device 130 can be in various forms such as a motor. The pulverizing box 110 is provided with a transverse partition plate 112 for supporting the telescopic rod piece 140 and the lower grinding disc 150. The two ends of the transverse partition plate 112 are respectively connected with ear plates 112a, and the two ear plates 112a are respectively fixed on the opposite two side walls of the pulverizing box 110 by bolts. In order to enhance the strength of the transverse partition plate 112, the transverse partition plate 112 can be set as a material of steel bar. The top of the transverse partition plate 112 is provided with a telescopic rod piece 140 for driving the lower grinding disc 150 to move up and down, and the end of the telescopic rod piece 140 is fixed with the lower grinding disc 150. The bottom of the upper grinding disc 120 is provided with a hemispherical groove 122, and the top of the lower grinding disc 150 is provided with a spherical protrusion 151 matched with the hemispherical groove 122. By setting the hemispherical groove 122 and the spherical protrusion 151, the lower grinding disc 150 and the upper grinding disc 120 have a larger close area, thereby facilitating the more efficient crushing of the granular feed. The spherical protrusion 151 and the hemispherical groove 122 have a gap, and the size of the gap between the spherical protrusion 151 and the hemispherical groove 122 can be appropriately adjusted according to the particle size of the required grinding material.A through feed hole 123 is formed at the center axis of the upper grinding disc 120, and a stirring rod 152 is fixedly connected to the spherical protrusion 151 and extends into the feed hole 123. During operation, the granular feed material to be crushed will enter the space between the spherical protrusion 151 and the semispherical groove 122 through the feed hole 123 and then be ground and crushed in this space. During this process, the telescopic rod 140 drives the lower grinding disc 150 to quickly lift and drop repeatedly within a certain interval, so that the stirring rod 152 is quickly extracted and inserted in the feed hole 123 within a cycle, further avoiding blockage in the feed hole 123. It should be noted that during the process of the telescopic rod 140 driving the lower grinding disc 150 to drop, the gap between the semispherical groove 122 and the spherical protrusion 151 will increase, and the granular feed material in the gap will quickly drop for a short time. However, since the telescopic rod 140 drives the lower grinding disc 150 to move repeatedly within a short cycle, the time is not enough for the feed material to completely slide from the feed hole 123 to the outside of the lower grinding disc 150, so the granular feed material will still be ground. The difference is that the feed material grinding time is shorter and the crushed particle size is larger within the non-telescopic rod 140 reciprocation cycle, but the size of the feed particle size is within the acceptable range for animal feed.
[0020] As can be seen from the above, in the embodiments of the present application, by setting the upper grinding disc 120 and the lower grinding disc 150 correspondingly, and by forming the semispherical groove 122 at the bottom of the upper grinding disc 120 and the spherical protrusion 151 at the top of the lower grinding disc 150, the area for grinding and crushing the granular feed material can be effectively increased to enhance the crushing effect. By setting the transverse partition plate 112, the telescopic rod 140 can be installed, and the telescopic rod 140 can drive the lower grinding disc 150 to move up and down repeatedly. In this process, the stirring rod 152 will be extracted and inserted in the feed hole 123, so as to scatter the granular feed material blocked in the feed hole 123 and keep the feed hole 123 unblocked. Further, the device can effectively enhance the grinding and crushing speed of the granular feed material, and the entire device does not use a vibration motor, so the damage to the device structure is small and does not affect the service life of the device.
[0021] In some embodiments, the driving device 130 includes a gear ring 131 sleeved on the outer periphery of the upper grinding disc 120, the gear ring 131 has teeth, a rotating motor 132 is arranged at the side wall of the crushing box 110, a drive gear 133 is coaxially connected to the output shaft of the rotating motor 132, and the drive gear 133 is engaged with the gear ring 131. In the embodiments of the present application, the rotating motor 132 can be two or more groups, the rotating motor 132 drives the drive gear 133, and the drive gear 133 can drive the upper grinding disc 120 to rotate, so as to realize extrusion and crushing of the granular material.
[0022] In some embodiments, the top of the pulverizing box 110 is provided with a feeding groove 113, the bottom of the feeding groove 113 is provided with a tapered discharging hole 114, and the bottom of the discharging hole 114 faces the guide hole 123. In the embodiments of the present application, the granular feed to be crushed can be fed into the pulverizing box 110 from the feeding groove 113.
[0023] In some embodiments, the stirring rod 152 is a hollow structure, the outer side of the stirring rod 152 is provided with a plurality of air outlets, the air pump 160 is arranged on one side of the pulverizing box 110, the air pump 160 is communicated with a gas supply pipe 161, the other end of the gas supply pipe 161 extends to the bottom of the lower grinding disc 150 and is communicated with the cavity of the stirring rod 152 upward. In the embodiments of the present application, the gas supply pipe 161 can deliver gas flow into the stirring rod 152, and the feed material blocked in the guide hole 123 can be blown away by the air outlets, so as to restore the circulation of the feed material in the guide hole 123.
[0024] In some embodiments, the telescopic rod is a telescopic cylinder, and the telescopic cylinder is communicated with the air pump 160 through a pipeline. In the embodiments of the present application, the telescopic cylinder can be supplied with air by the air pump 160, and the gas flow in the telescopic cylinder and the stirring rod 152 can be supplied with air by the air pump 160.
[0025] In some embodiments, the transverse partition plate 112 is a mesh plate structure, and a plurality of material leakage holes 112b are uniformly arranged on the transverse partition plate 112. In the embodiments of the present application, through the above arrangement, the material will not easily accumulate on the transverse partition plate 112, thereby reducing the cleaning difficulty.
